GUN SILENCER, FLASH COVER, AND RECOIL CHECK.

Application filed April 18, 1921.

To all whom it may concern .Be'it known that I, GEORGE A. GooowiN, acitizen of the United States, residing at Dayton, in the county ofMontgomery and State of Ohio, have invented certain new and usefulImprovements in Gun Silencers, Flash Covers, and Recoil Checks, of whichthe following is a specification.

This invention relates to silencers in general and more specifically toa silencer for firearms.

In the conventional type of gun silencer no specific means have beenprovided for the elimination of a visible flash caused by the explodedgases. In using such type of silencer at night the noise of suchexplosion would be eliminated but the resulting flash would disclose thelocation of the firearm. It will be readily seen that the elimination ofboth the noise and flash would be great advantage in actual warfare.

It is therefore proposed to provide a gun silencer which will beinexpensive, easily constructed, readily attached to the firearm, and soconstructed as to eliminate any flash or noise.

Referring more particularly to the attached drawings, the figure is aside elevat-ion, partly in section, of the invention, showing itsattachment to the gun barrel, and also the interior of the silencer.

The gun barrel A is recessed as at P and provided with an interior screwthread D to receive the exterior screw thread C- of the coupling B.Connected to the opposite end of the coupling member B is a hollowcasing K provided with apertures L. Baflles H are mounted interiorly ofthe casing K by means of flanges I integral with said baflles H. Theflanges I are provided with apertures J so positioned as to communicatewith the apertures L. Mounted exteriorly of the casing K is an outercasing M which is provided with an inturned flange R overlapping thedownwardly extending flange Q of the casing K.

Thus it will be seen that upon firing, the bullet passes through thecentral passages E, E, and F of B, H, and M respectively. The gases,however, expand as they pass through the enlarged passage G of thecoupling member B. As the gases pass forward they strike against thebaflles H, are temporarily reversed in their direction, and as theyfurther expand, find an outlet through the corresponding apertures J andSerial No. 462,292.

Furthermore, when this device is applied to automatic rifles, it notonly accomplishes the features above set forth but also affords a meansof diminishing the travel of the recoil mechanism thereby increasingtherate output of shots in a given'time.

Having thus described my invention, I claim:

1. In a gun silencer an inner casing provided with an inlet and outletin horizontal alignment for the passage of a bullet, and a plurality oflaterally disposed apertures, a plurality of angularly disposed andcentrally apertured baffles provided with flanges parallel to andconnected to the inneiwalls of said inner casing and provided withlaterally disposed apertures in register with those of said innercasing, an outer casing arranged about and connected to said innercasing at its discharge end, said outer casing having a dischargeopening arranged at its rear end and annularly about said gas inlet.

2. In combination, an interiorly screwthreaded gun barrel, an exteriorlyscrewthreaded hollow .sleeve adapted tobe screwed therein, a nutintegral with sleeve, a hollow extension beyond said nut, the passagethrough said hollow extension'being venturi -shaped, a' gun silencerbeing detachably secured to said sleeve extension.

3. In combination, an interiorly screwthreaded gun barrel, an exteriorlyscrewthreaded hollow sleeve adapted to be screwed therein, a nutintegral with sleeve, a hollow extension beyond said nut, the pets sagethrough said hollow extension being venturi-shaped, a gun silencerbeingdetachably secured to said sleeve extension, said gun silencercomprising an inner casing provided with an inlet and outlet inhorizontal alignment for ,the passage of a bullet, said inner casingbeing further provided with a plurality of laterally disposed apertures,a inner casing at its discharge end, said outer plurality of angular-1ydisposed and cencasing having a discharge opening arranged l0 trallyapertured bafiles provided With at itsrear end and annularly about saidgas flanges parallel to and connected to the ininlet.

ner walls of said inner casing and provided In testimony whereof I haveafiixed my With laterally disposed apertures in register signature.

with those of said inner casing, an outer casing arranged about andconnected to said GEORGE A. GQODWIN.
